501(c)(3)

Section 501(c)(3) is the most common and most donor-friendly tax-exempt classification in the United States. Organizations qualifying under this section include charities, churches, hospitals, universities, museums, and other entities organized and operated exclusively for religious, charitable, scientific, literary, or educational purposes. The key benefit for donors is that contributions to 501(c)(3) organizations are tax-deductible on federal income tax returns, subject to adjusted gross income limitations. In exchange for this favorable treatment, 501(c)(3) organizations face significant restrictions: they cannot participate in political campaigns, their lobbying activities must remain insubstantial, and no part of their net earnings may inure to the benefit of private individuals (the "private inurement" prohibition). There are two subcategories within 501(c)(3): public charities, which receive broad public support, and private foundations, which are typically funded by a single source such as a family or corporation. Most of the nonprofits tracked on NonprofitTruth are public charities classified under 501(c)(3). Organizations can verify their 501(c)(3) status through the IRS Tax Exempt Organization Search tool, and donors should confirm this status before claiming any charitable deduction.
